Thanks for the reply. Can u give me a sample function? I tried to add rendrer but it only renders the data not summary. I wrote the summary renderer like thissummaryRenderer: function(value, summaryData, dataIndex) {

I'm sorry Rama, but I just don't have the time these days to go deep into this.
You will need to gain understanding of how this works by using a debugger, e.g. Firebug or the Google Chrome developer tools. It's hard, but it'll serve you in the long run.
